29th International Cosmic Ray Conference Pune (2005) 00, xxx–xxx Large-scale anisotropy of EGRET gamma ray sources

By Luis Anchordoqui A, Thomas Mccauley B, Thomas Paul A, Olaf Reimer C and Diego F. Torres D


In the course of its operation, the EGRET experiment detected high-energy γ-ray sources at energies above 100 MeV over the whole sky. In this communication, we search for large-scale anisotropy patterns among the catalogued EGRET sources using an expansion in spherical harmonics, accounting for EGRET’s highly non-uniform exposure. We find significant excess in the quadrupole and octopole moments. This is consistent with the hypothesis that, in addition to the galactic plane, a second mid-latitude (5 ◦ < |b | < 30 ◦ ) population
